Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.Chalcogenide optical PCMs have gathered interest for their potential in compact, non‐volatile optics and photonics. Free‐space PCM metasurfaces require new considerations from phase change memory that need to be addressed for reliable scale‐up. Several failure mechanisms pertaining to free‐space PCM devices and layout methods are isolated to prevent ...

Advanced Photonics Research, EarlyView.The change in the dielectric function from the heat‐driven amorphous‐to‐crystal Si transformation can be used to engineer large spectral adjustability of Si‐based multilayered narrowband photonic devices operating in the IR region. This effect can be utilized to accurately adjust the resonance wavelength of fabricated amorphous multilayered structures ...

Discovery of Volatile Gas in the Giant Impact Disk Around the 150 Myr Old HD 23514
The Astrophysical Journal LettersWe report the discovery of CO _2 gas emission around HD 23514, an F5V star in the ∼150 Myr old Pleiades cluster, hosting one of the rare giant-impact disks with unique mineralogy dominated by silica dust. We show that the dust feature remains stable over

Seismic Oscillations Excited by Giant Impacts in Directly Imaged Giant Planets
The Astrophysical JournalThe radii and masses of many giant exoplanets imply their interiors each contain more than ∼100 M _⊕ of solids. A large metal content may arise when a giant planet grows by colliding and merging with multiple ∼10 M _⊕ solid cores.

Advanced Science, EarlyView.Laser ultrasound super‐resolution imaging (LUSSI) leverages laser‐generated ultrasound for functional 3D transcranial imaging of brain tumor vasculature. Combined with optoacoustic tomography, it is demonstrated in a glioblastoma model, revealing structural abnormalities, compressed vessels, hemorrhages, and hypoxic regions.
